Programming manual - where?

[Dan Oelke]

I have a need to hack the driver for a specialized application 
using the 3c905B-FX card.  *Hopefully* the card will do what
I want it to - but I need to see a register map first.  

In case anyone knows - is there a way to turn off the 
transmitter completely - so the fiber goes completely dark,
under software control?

Where or how do I get hold of a copy of the programming manual
for these cards? Searching 3com's web site has not worked for me.  

Thanks,
Dan
